If it is, immediately replace the gasket, otherwise the vacuum pad may not hold the rig securely. To replace the gasket, see "Replacing Vacuum Pad Gaskets" in the "Maintenance" section. See "Accessories" for gasket part number. 1. To use the vacuum pad, tilt the base of the rig and slide the vacuum pad under it so the threaded stud goes through the hole on the end of the center slot on the base. Then set the stand upright. 2. Position the rig as required for coring the hole. 3. Level the rig with the four (4) leveling screws using the bubble level (4125 & 4130 only) as a guide. When the rig is level, tighten the four (4) nuts (4125 & 4130 only) on the leveling screws. 4. Connect one end of the supplied vacuum hose to the vacuum line coupler on the vacuum pad. To do this, pull back the collar on the hose and push the end of the hose onto the coupler until in snaps into place. Then, connect the other end of the vacuum hose to the coupler on the vacuum pump following the same procedure. 5. The vacuum pump may be set on a dry surface away from the rig or mounted to the base of the Dymorig as shown. However, DO NOT mount the vacuum pump to the Dymorig when angle coring. To mount the vacuum pump on the Dymorig, place the small hole on the vacuum pump mounting bracket over the vacuum pad stud on the Dymorig. 6. Plug the vacuum pump into the power source—the pump will start 7. Leveling Screws Rod or Bolt Fig. 13 WARNING! The vacuum gauge must read a minimum of 20 inches of mercury vacuum. To reduce the risk of injury DO NOT CORE if the gauge reads less than 20 inches of mercury vacuum. automatically. Step on the vacuum pad or the vacuum pad stud until the vacuum pad lowers and adheres to the work surface. After the pad is secured to at least 20 inches of mercury vacuum, tighten the vacuum pad nut securely. Using an Expansion-Type Anchor (Fig. 13) For Cat. No. 4115 & 4120 only. Use a 5/8" expansion-type anchor (not supplied) that will accept a 5/8" threaded rod or bolt to secure the base to the work surface. 1. Remove the rubber gasket from the base. 2. Level the rig with the four (4) leveling screws. 3. Using an expansion-type anchor, insert a threaded rod or bolt through the slot located in the base of the Dymorig and tighten the bolt or washer and nut firmly in the anchor following the manufacturer's instructions.
